Speed.io is a modern DSL speed test to analyze your broadband internet access.
If you find that your internet connection is too slow or you are just curious how fast it really is -
speed.io is a perfect tool for a fast speed check - worldwide.

Speed.io measures your current internet speed to the server closest to you ("nearest server" is not wrong but the other way sounds more eloquent)
(we have almost 50.000 servers worldwide). We test your download (speed with which you receive data from the internet), upload (speed with which you send
data to the internet), connection (maximal number of connections per minute) as well as ping (response time between your computer and the internet).

All tests are performed within your browser over HTTP (TCP) and require no further software other (same issue as with "nearest server")
than a newer browser with activated Flash.

You can test all kind of connections (LTE, UMTS, GPRS, ISDN, DSL, VDSL or cable).

The speed test from speed.io tells you just how fast your connection is
In today’s digital age, the strength and speed of your internet connection is an important part of professional and private life. Whether broadband, fibre, 3G, HSPA or 4G, the speed test from speed.io tests your connection, allowing you to verify whether or not your provider is giving you the service you’re paying for. Our speed test is also useful for those who want to compare internet packages. Armed with the test results from your speed test, you can optimise your connection and get the most out of your online experience.

How does the speed test work?

The speed test gives you the tools you need to run the test entirely in your browser. All you need is a Flash plugin—Speedtest takes care of all the rest. Simply ensure that your computer or mobile phone / tablet is connected to the internet either directly via a router with a network cable or via a WiFi network and press the start button on the speed.io website. The test program then establishes a link with three nearby servers and measures the speed of your broadband / fibre / wireless connection.

What do the test results mean?

The test results for your broadband or wireless network are broken down into four parts: download, upload, connects, and pings. The download value tells you how much data your WiFi or broadband connection can move from the World Wide Web to your computer. The upload value indicates how quickly you can transfer files from your computer, which is important to know for those who regularly use cloud services to store files. Connects show you the number of connections that can be established simultaneously, and the higher the value, the better. Pings refer to the response delay, which is particularly interesting to gamers. Here, lower values are preferable.

What data transfer rates should you expect to see in the test results?

Your maximum possible data transmission speed depends on whether you have a broadband, fibre, WiFi or another connection, as well as your pricing plan and service provider. The following is an overview of the theoretical highest download speeds so you can compare your test results to see just how well your speed measures up.
